The answer would be H. You can immediately eliminate F and J because they do not include the $10 fee and $39 is the amount charged for one book.
Her total allowance as a fraction could be expressed by 9/9. When you subtract the amount that she used, 4/9, you are left with 5/9, which is the solution.
Answer: C. Independent equations.
Hope tis helps you out.
Answer: it is invalid
Step-by-step explanation: it is invalid because the data table has 30 out of 100 people stating that they prefer to view movies in theater. This does not have the same ratio as 300 out of 400, and would only work had he said 300 out of 1000. Thus, he is incorrect in his inference.
So,
I'm assuming you want me to make a formula for figuring your points after any given month assuming that you use the site at least once a month and you don't spend your points.
After one month, you will have your base 100 points plus an additional 10 points.
100 + 10 = 110
After two months, you will have gained an additional 10.
110 + 10 = 120
We can put this into a function, where P is your points, and m is the number of months you use the site.
P(x) = 100 + 10m
So after 500 months, you will have:
P(x) = 100 + 10(500) = 5100 points!
This is identical with:
y = 100 + 10m
and
y = 10m + 100
So this can be graphed as a linear equation/function with a y-intercept of 100 and a slope of 10/1.
